During 1971 and 1972, 71 cultures of neisseriae that attacked lactose were received by this laboratory. All strains except one from an eye swab were from the nasopharynx of healthy subjects. Nineteen similar strains from the nasopharynx were isolated in this laboratory. The characteristics of these strains were compared with those of Neisseria meningitidis, Neisseria pharyngis, Neisseria catarrhalis, and Neisseria lactamicus. The 90 strains under investigation closely resembled Neisseria meningitidis but could be differentiated by production of acid from lactose and beta-galactosidase activity and were therefore classified as Neisseria lactamicus.
1971年至1972年期间,本实验室收到了71株能分解乳糖的奈瑟菌培养物。除了一份眼拭子样本中的菌株外,所有菌株均来自健康受试者的鼻咽部。本实验室从鼻咽部分离出19株类似菌株。将这些菌株的特征与脑膜炎奈瑟菌、咽奈瑟菌、卡他莫拉菌和产乳酸奈瑟菌的特征进行了比较。所研究的90株菌株与脑膜炎奈瑟菌极为相似,但可通过乳糖产酸和β-半乳糖苷酶活性进行区分,因此被归类为产乳酸奈瑟菌。
